Sorry but you are wrong.
The payment of YoBit signature campaign comes to Yobit account.
You can not change your password or e-mail in account options (pass only by email).
If someone made account with own e-mail and not give password - OP can do nothing.
It seems to me that OP didn't realise that.
First he must make own emails and then ask people to open an accounts.
In other words - this thread is pointless.
this thread was pointless from the start, since OP is just a newbie member and he has never proven that he is willing to pay since he didn't provide escrow and i think somebody already gave him the accounts without realizing this and got screwed.
I made him an account, I gave him my email address, username and password. But it does not make sense. He can not change password or email address, because he don't have access to my email. Only I can do that, so either way I'll always have access to this account. (Unless I give him password to my email)
